[PATCH v2 2/5] BaseTools/header.makefile: remove "-c" from BUILD_CFLAGS

[Laszlo Ersek <lersek@redhat.com>]

Option "-c" is a mode selection flag (choosing between compiling and
linking); it should not be in BUILD_CFLAGS, which applies only to
compiling anyway. The compilation rule for C source files, in
"footer.makefile", already includes "-c" -- currently we have double "-c"
options.

This patch doesn't change behavior.
